Firefox nightly <-> Chrome

For people using SIP as signaling protocol and a bit frustrated that
RTCWeb implementations from Mozilla and Google are not compatible yet,
we've updated our open source projects (sipml5.org and
webrtc2sip.org).
sipml5 allows Chome2Chrome and Firefox2Firefox calls without any
gateway. To make calls between Chrome and Firefox you will need the
enable the RTCWeb breaker from open source webrtc2sip gateway as
explained in the documentation.
